Abstract 138: Factors Influencing the Quality of Continuous Chest Compressions
Introduction: There are several factors can to influence the quality of chest compressions.
Hypothesis: We hypothesized that factors such as gender, body mass index and practice of physical activity can influence the quality chest compressions.
Materials and methods: We trained 158 first year medical students using the “Family and Friends CPR Anytime” course. After 30 minutes, subjects performed two minutes of continuous chest compressions (CCC) on a Resusci Anne Skill Reporter manikin. All students had their weight and height measured allowing for the calculation of BMI and answered a identification questionnaire.
Results: Comparing the genders, the mean of percentage of compressions with depth > 38 mm, the percentage of chest compressions with adequate depth and the average depth were better performed by male gender. Comparing normal BMI group and overweight group, the percentage of chest compressions with adequate depth, the average depth and the mean of percentage of compressions with depth > 38 mm were significant better in overweight group. Individuals who practice regular exercise were significant better in the following parameters: compressions/minute, percentage of chest compressions with adequate depth and the average depth. Table 1 shows the means and p-values of chest compressions.
Conclusion: The results showed the quality of chest compressions may be influenced when performed by individuals of different genders, BMI, and performing regular physical activity or not. Therefore, it is important that studies that assess the quality of chest compression, particularly CCC, heed these variables, as they may influence the results.
